' Application filed November 7, 1883. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM LEVERTON BEA'r'rY, HARVEY LEGRAND BEATTY,and ALVIN OSCAR BEATTY, allmanufacturers, and all of the town ofWelland, in the county of W'elland, in the Province of Ontario, Canada,have jointly invented certainnew and useful Improvements inHoisting-Machines; and we do hereby declare that the following is afull, clear, and exact description of the same.

The invent'ionrelates to that class of hoisting-machines in which therope-drum is connected to the driving-axle by an adjustablefriction-clutch;'and the object of the'invention is to improve the formand construction of the friction-clutch, and also to devise simplemechanism by which the speed of the ropedrum can be increased withoutaltering the speed of the driving-axle. 1

Figure l is a perspective view of our improved hoisting-machine. Fig. 2isa perspective end view, showing the gearing for in creasing the speedof the ropedrum. Fig. 3 is a sectional detail, showing the form offriction-clutch for connectingthe drum to the machinery for increasingits speed. Fig. 4 is a sectional detail of the friction-clutch forform-v ing a direct connection between the drivingshaft and rope-drum.Fig. 5; is a front detail View of the disk, showing the form ofoctagonal flange, with the blocks of wood attached to it. Fig. 6 is afront view of the fastspeed drivinggear, showing the form of thecam-adjuster for throwing it inand out of gear. Fig. 7 is a plan of ourmachine, showing the fast-speed clutch mechanism in section. Fig. 8 is alongitudinal sectional elevation of our machine.

We have shown a number of different views of our machine, in order tofully illustrate our invention; but for the general purpose of thisspecification, Figs. 7 and 8 will mostly be referred to, unless theother figures are specifically designated.

A is the rope-drum driving-axle, suitably journaled at either end on thepedestals B, which form part of the main frame of the machine. We haveshown two rope-drums, G,

" on the axle A; but it will be understood from the drawings that one ofthese rope-drums might be dispensed with without altering our invention,and therefore, although we may only speak of one drum and itsconnections, it will be understood that one ismerely aduplicate of theother, and, so far as its connections with the driving-axle orotherdriving-gear is concerned, one, two, orzmore drums with connectionsmight be used in the hoisting-machine without altering the generalarrangement of our invention. The rope-drum Ois journaled loosely onitheaxle A; butits inner flange has a recessed head, D, shaped to formthe'female half of the'friction-clutch, the other half of the clutchbeing formed, as hereinafter described, on the disk E, which isikeyed orotherwisezrigidly fastened toithe driving-axlev A. A'beveled-gear wheel,F, is formed upon or attached to one side of the disk E,-and is arrangedto mesh with thelloeveled pinion G,

which is fastened to the vertical shaft H. This latter shaft is properlyjo'urnaled in and sup-' ported by the bracket I, which forms part ofthemain frame of the machine. The vertical" shaft H derives its motionfrom any suitable motor; andv through its connection described with theaxle 'A the motion of the drivingmotor is conveyed to the rope-drumdrivingaxle A. So long as the connectionbetween the recessed head D and.the disk E is broken, the axle A will revolve without communicatingmotion to the drum, unless the said drum is connected to the shaft bythe fast-driving gear, which we will describe hereinafter.

On reference to Figs. 4, 5, and 8 the construction of the friction-faceof the disk E will be understood. This disk E has a flange, 6, extendingoutwardly at right angles from its surface and a'short distance belowits periphery. This flange is octagonal in shape, and is designed toreceive a block of wood, f, on each octagonal side. The said blocks,when bolted in position, as shown in Fig. 4., are arranged so thatthe-grain of the wood shall extend outwardly toward the periphery of thedisk. The blocks are then turned down on a bevel extending from theperiphery of the disk toward the outer edge of the flange c, the bevelof the blocks being formed to correspond with and fit into theconically-recessed head D- This form of clutch is exceptionally strong.The octagonal shape of the disk constitutes a substantial IOO seat foreach block, which tends to hold each block in position and relieves in agreat measure the strain which the bolts used for securing the blocks tothe disks would otherwise be called upon to sustain.

On reference to Fig. 8 it will be noticed that we make an elongatedkeyway, J, through the axle A, at the outer end of the drum 0. Thiskeyway has fitted into it a key, K, which passes through a collar adjustabl y fitted on the driving-axle A, but prevented from revolvingthereon by the key K. The elongated keyway J permits the longitudinaladjustment of the key K and the collar L, connected to it. Thislongitudinal adjustment is effected by the spindle M, which fits into ahole in the axle A, extending from its end to the keyway J, as shown inFig. 8. The outer end of this spindle M bears against the screw m, whichfits into a nut, N, formed in or attached to the frame of the machine,as shown. It will thus be seen that by turning the screw m the pressureimparted by it through the spindle M against the key K is transferredthrough the collar L to the end of the rope-drum G, causing therope-drum to move longitudinally upon the axle A, forcing itsconically-recessed head D onto the disk E, thereby effecting africtionclutch between the drum 0 and the said disk E, whichfriction-clutch causes the drum 0 to revolve with the axle A, as beforespecified.

\Vith the view of enabling the ready adjustment of the spindle M weattach to the outer end of the screw in an arm, 0. This arm 0 isconnected by the rod 1 to the rock-shalt Q, which rock-shaft isjournaled in the front of the frame of the machine, as shown in Fig. 1,and is provided with. a suitable handle for rocking it in its journal,which rocking motion is sufficient to turn the screw in its nut, inorder to impart the desired adjustment to the drum, as specified.

The connection herein described between the drum G and disk E is made,as specified, when it is desired to use the drum for hoisting a weight.

In order to run the drum quicker, with the View of taking up slack orfor any other purpose, the connection between the drum 0 and disk E isbroken, when, by throwing the fastspeed gear, which we shall nowdescribe, into connection with the drum, the said drum is caused torevolve at the desired high speed.

Figs. 2, 3, 6, and 7 exhibit the arrangement and construction ofthefast-driving gear.

A gear-wheel, R, is keyed or otherwise fastened to the axle A. Thisgear-wheel is arranged to mesh with the pinion S, keyed or otherwisefastened to the counter-shalt T, which counter-shaft is suitablyjournaled in brackets attached to the frame of the machine, asrepresented. A beveled disk, U, is also fastened to the counter-shaft T.This beveled disk is designed to fit into' the conically-recessed diskV, which disk revolves freely on the counter-shaft T, unless afriction-clutch is formed between it and the beveled disk U. Aspur-whceLlV, is either connected to or formed upon the disk V, whichspur-wheel meshes with the pinion X, which is fastened to the drum 0, asshown. From this description it will be seen that when the connectionbetween the drum 0 and the disk E is broken and a clutch-connectionformed between the disks U and Vthe speed of the drum will be greaterthan the speed of the axle A, which speed is according to the relativesizes of the gear-.

ing connecting the axle A, through the counter-shaft T, to the drum G.In order to effect this connection between the disks U and V easilyand-effectnally, we provide a handle, Y, which is attached, as shown, toa cam-faced collar, Z, jonrnaled on the counter-shaft T. The face ofthis cam-faced collar Z is arranged to work against a similarly-formedcam on the frame of the machine, so that by turning the cam-faced collarZ by its handle Y the collar Z is pushed away front the frame from theposition it is shown in Fig. 3 to the position it is shown in Fig. 7. Bythus moving the collar, which acts against the hub of the disk V thesaid disk is forced against the disk U, and in this manner the desiredconnection is effected.

\Ve should mention here that the surface of the recessed disk V isprovided with a pa per lining, o, pressed into it, as indicated, and itrequired, otherwise secured to the said disk.

A paper lining of this kind constitutes an admirable frictiolrsui'face,and when worn can readily be replaced' \Vhat we claim as our inventionis 1.
